Research Abstract |
We have characterized of Legionella pneumophila hyper-toxic mutants which are intracellular growth-deficient (Toxh mutants) for infectivity and cytotoxicity to host cells. And the chromosomal loci of mini-Tn10::kan-insertion in Toxh mutants and a gene responsible for a phenotype of one of their mutants have identified. Furthermore, pathogenisity of Toxh mutants were evaluated using A/J mice, which are susceptible to replicative L. pneumophila infections.
